我有一个无法运行的迁移。Laravel迁移失败,但查询无效

public function up() 
{ 
    Schema::create('users_watch_history', function (Blueprint $table) { 
     $table->string('id', 36)->primary(); 
     $table->string('user_id', 36); 
     $table->string('video_id', 36); 
     $table->string('course_id', 36); 
     $table->timestamp('last_timestamp'); 
     $table->float('vid_watch', 5, 2); 
     $table->float('total_watch', 5, 2); 
     $table->text('watched_parts'); 
     $table->integer('last_position'); 
     $table->softDeletes(); 

     $table->foreign('user_id') 
      ->references('id')->on('users') 
      ->onDelete('cascade')->onUpdate('cascade'); 

     $table->foreign('video_id') 
      ->references('id')->on('videos') 
      ->onDelete('cascade')->onUpdate('cascade'); 

     $table->foreign('course_id') 
      ->references('id')->on('courses') 
      ->onDelete('cascade')->onUpdate('cascade'); 
    }); 
} 

当迁移实际上是跑我不断收到有关的last_timestamp列无效的默认值的错误消息。

$ php artisan migrate 


    [Illuminate\Database\QueryException] 
    SQLSTATE[42000]: Syntax error or access violation: 1067 Invalid 
    default value for 'last_timestamp' (SQL: create table 
    `users_watch_history` (`id` varchar(36) not null, `user_id` 
    varchar(36) not null, `video_id` varchar(36) not null, `course_id` 
    varchar(36) not null, `last_timestamp` timestamp not null, 
    `vid_watch` double(5, 2) not null, `total_watch` double(5, 2) not 
    null, `watched_parts` text not null, `last_position` int not null, 
    `deleted_at` timestamp null) default character set utf8 collate utf8_unicode_ci) 



    [PDOException] 
    SQLSTATE[42000]: Syntax error or access violation: 1067 Invalid default value for 'last_timestamp' 

我的MySQL版本

> select @@version 
+------------+ 
| @@version | 
+------------+ 
| 5.6.34-log | 
+------------+ 
1 row in set (0.20 sec) 

但是,这扔我的曲线是扭曲 - 如果我运行在CLI创建命令为DB,一切工作正常?

> create table `users_watch_history` (`id` varchar(36) not null, `user_id` varchar(36) not null, `video_id` varchar(36) not null, `course_id` varchar(36) not null, `last_timestamp` timestamp not null, `vid_watch` double(5, 2) not null, `total_watch` double(5, 2) not null, `watched_parts` text not null, `last_position` int not null, `deleted_at` timestamp null) default character set utf8 collate utf8_unicode_ci; 
Query OK, 0 rows affected (0.19 sec) 

表模式:

> show create table users_watch_history \G 
*************************** 1. row *************************** 
     Table: users_watch_history 
Create Table: CREATE TABLE `users_watch_history` (
    `id` varchar(36) COLLATE utf8_unicode_ci NOT NULL, 
    `user_id` varchar(36) COLLATE utf8_unicode_ci NOT NULL, 
    `video_id` varchar(36) COLLATE utf8_unicode_ci NOT NULL, 
    `course_id` varchar(36) COLLATE utf8_unicode_ci NOT NULL, 
    `last_timestamp` timestamp NOT NULL, 
    `vid_watch` double(5,2) NOT NULL, 
    `total_watch` double(5,2) NOT NULL, 
    `watched_parts` text COLLATE utf8_unicode_ci NOT NULL, 
    `last_position` int(11) NOT NULL, 
    `deleted_at` timestamp NULL DEFAULT NULL 
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci 
1 row in set (0.17 sec) 

任何想法,这可能是造成这种有效的查询不通过迁移运行?

检查你的'explicit_defaults_for_timestamp' MySQL变量。控制台和项目之间的区别可能在于不同的环境(对于该变量具有不同的值)。 https://dev.mysql.com/doc/refman/5.7/en/server-system-variables.html#sysvar_explicit_defaults_for_timestamp – Axalix

禁用MySQL严格模式。

  • 在你laravel配置文件database.php,设置 'strict' => true 为' strict' => false
  • 或添加nullable()$table->timestamp('last_timestamp')->nullable();

    其中一个 的应该解决的问题。
